Verrucomicrobiota is a phylum of Gram-negative bacteria that contains only a few described species. The species identified have been isolated from fresh water, marine and soil environments and human faeces. A number of as-yet uncultivated species have been identified in association with eukaryotic hosts including extrusive explosive ...
The PVC superphylum is a superphylum of bacteria named after its three important members, Planctomycetota, Verrucomicrobiota, and Chlamydiota. [2] [3] Cavalier-Smith postulated that the PVC bacteria probably lost or reduced their peptidoglycan cell wall twice. [4] It has been hypothesised that a member of the PVC clade might have been the host ...
Akkermansia is a genus in the phylum Verrucomicrobiota ( Bacteria ). [ 2] The genus was first proposed by Derrien et al. (2004), with the type species Akkermansia muciniphila (gen. nov., sp. nov). [ 1] Until 2016 the genus contained a single known species, namely A. muciniphila. [ 2] In 2016, Akkermansia glycaniphila was isolated in the feces ...
Planctomycetota have also been associated with lichen communities and Sphagnum wetlands. Sphagnum wetlands store large amounts of carbon, contributing to the global carbon cycle. Planctomycetota play a considerable role in the degradation of sphagnum, accounting for roughly 15% of the bacterial community. [ 8]
Bacterial phyla constitute the major lineages of the domain Bacteria. While the exact definition of a bacterial phylum is debated, a popular definition is that a bacterial phylum is a monophyletic lineage of bacteria whose 16S rRNA genes share a pairwise sequence identity of ~75% or less with those of the members of other bacterial phyla.
Bacteroidota. The phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals.
Victivallis vadensis is a Gram-negative, coccus-shaped, bacteria found in the human digestive tract. [1] It measures approximately 0.5-1.3 micrometers in diameter, is non-motile and chemoorganotrophic, and does not form spores. [2] Victivallis vadensis is strictly anaerobic, as are 90 percent of the bacteria in the human gastrointestinal system.
Verrucomicrobium spinosum is a species of bacteria, which was isolated and described by Heinz Schlesner in 1987. It was the first named organism of what is now the phylum Verrucomicrobiota described by Hedlund, Gosink and J. T. Staley in 1996. Prosthecobacter fusiformis which was isolated by Jan De Bont (DeBont and Staley, 1971) was the first ...
